The word classified means a lot of different things depending on the context but when it comes to computer hardware it means one thing, the best of the best from EVGA.  Most enthusiasts are very aware of EVGA since it is their classified series of products that frequently are used for world record benchmark runs.  Founded in 1999 they have grown from a system builder into a manufacturer of Intel and NVIDIA products.  They are also the geniuses behind the mega powerful Classified SR-2 motherboard just in case you really need to run dual Xeon's.
